Silverline Subaru BMR Racing's Colin Turkington defied his Silverstone grid penalty after stringing together what the former double champion believes was one of his strongest weekends so far of his British Touring Car season.

Turkington started the day plum last but immediately rose forward to a scarcely believable eighth place result in race one.

With his rescue almost complete, Turkington very nearly earned himself a podium finish during the following race but the Subaru Levorg driver settled for a pair of fourth place finishes, which has kept him within a mathematical shout of lifting a third BTCC title at Brands Hatch.

37-points adrift of championship leader Sam Tordoff, the 34-year old still remains Subaru's best chance of the famous Japanese manufacturer capturing the drivers' title in their year of BTCC competition.

"It's funny how things worked out. It was one of my better weekends. Consistent scoring over three races. Apart from Oulton Park and Croft, that could be the next best one. Things just fell my way," Turkington said.

"We had a good car, kept working and took advantage when others had issues. We've come away having had a strong weekend.

"It was 19 positions [in race one]. Some I really had to earn but others also had mishaps. I thought here of all places would make things really difficult."

Having calculated where his Levorg was particularly strong, Turkington managed to nullify Subaru's current straight-line speed pitfall and made a number of typically clinical moves through the final Brooklands and Luffield complex throughout the three races.

"There's only four corners and you're limiting you're overtaking opportunities but the car was strong in the right places.

"Particularly towards the end of the races I still had a strong car whereas the FWD cars on the softs where dropping quite quickly so I had to be patient in picking my moments.

"Every corner is an opportunity. My car was really strong on the exit of turn three so if you can get a bit of an overlap that tees things up nicely going into the complex. It was a game a chess really."
